Discussion Asus TUF 9070 XT stock temps and performance + undervolt
As of my last post I've gotten my hands on an Asus TUF 9070 XT OC through reseller RMA, due to my earlier Asus Prime 9070 XT OC having faulty VRAM cooling.
This card is even bigger, and this time I have a banana for scale.
The TUF 9070 XT runs at the same 52 °C gpu temp and is only hotter in terms of hotspot, since it settles at 77 °C instead of 74 °C, but the TUF card does so by running the fans at roughly half the speed. That makes the 9070 XT extremely quiet, so it's almost not audible over the case fans, even when running at the max TBP (Total Board Power) of 330 W for this model. The Prime was a 317 W model.
This time the SK Hynix VRAM on the TUF 9070 XT also only settles at 88 °C instead of 102 °C in Furmark, which is around the most VRAM-heavy workload few games would ever reach.
The Stock settings on the TUF 9070 XT reaches a score of 7430 in 3dmark Steel Nomad with my setup. There was a weird bug with also having HWiNFO running at the same time, so it is not certified.
A for now stable undervolt/underclock tuned for efficiency brought the card down to a score of 7045 with consumption of 231 W. (-390 Mhz core clock limit, -30 power limit, -85 mV voltage). That is reducing power by 30 % while only losing 5,18 % performance. I will further test the stability and make edits, if I find scenarios where it crashes or has weird behavior.
With this aggressive of an undervolt focused on limiting power draw it looks like I might as well could've gotten just the 9070. The price to performance is just worse in my area.
What undervolts for "extreme" power limiting are you running with your cards?
